I'm not sure I can, you see: in fixing read, my original failed execution 
now works.  It was a write, backspace, read, write - where the second write 
fails.  Is it possible that calling:

   rc = ioctl (fh, MTIOCTOP, (char*)&opblk);

simply resets the error (generated by the old read() routine) and that's why 
I thought it needed it?

Thanks for fixing the main issue, your support is very good and welcome!
Jason.
